There are contrary opinions regarding the surgical treatment of pulmonary hydatid cysts. We report our experience performing a modified version of uncapitonnage surgery, called “saucerization,” for treating pulmonary hydatid cysts.
Methods
A total of 78 patients with pulmonary hydatid cysts were studied regarding their surgery outcome and the complication rate. The procedure used for cyst evacuation depended on whether the cyst had ruptured. If ruptured, cystotomy was done; otherwise, enucleation was preferred. To deal with the residual cavity in an uncapitonnage manner, we removed the thin margins of the pericyst and closed the bronchial openings at the cavity floor. All patients were followed up at least for 6 months.
Results
The intensive care unit stay ranged from 1 to 9 days. Incomplete lung expansion (six patients) was the main postoperative complication followed by wound infection (four patients) and persistent air leak (≥7 days) (one patient). There was one death. Dependence on mechanical ventilation and subsequent septic shock were also observed. The other patients exhibited no complications during the follow-up period.
Conclusions
Our experience demonstrated a low complication rate associated with removing the thin margins of the residual cavity and changing the shape of it into a “saucer.” The results were satisfactory and comparable to the results of other studies on pulmonary hydatid cysts. 相似文献
Introduction: Usnic acid (UA) is a lichen-derived secondary metabolite with a unique dibenzofuran skeleton and is commonly found in lichenized fungi of the genera Usnea and Cladonia. Usnic acid has been incorporated for years in cosmetics, perfumery, and traditional medicines. It has a wide range of bioactivities, including antimicrobial, antiviral, anticancer, anti-inflammatory properties.
Areas covered: This review covers patents on therapeutic activities of UA and its synthetic derivatives published during the period 2000–2017.
Expert opinion: UA demonstrates excellent anticancer and antimicrobial properties. However, its application was withdrawn due to acute liver toxicity reported with chronic consumption. The broad spectrum of its biological activity indicates high the variability of UA’s binding preferences. The main idea to be addressed in the future should include the synthesis of UA derivatives because these might possess increased bioactivity, bioavailability and decreased toxicity. It is noteworthy that UA derivatives possessed better antibacterial, antitubercular, and anticancer activity than the parent compound . Most importantly, UA and its analogs (to a greater extent than UA) can be useful in cancer drug treatment. They have the potential for joint application with other anticancer drugs in order to overcome drug resistance. 相似文献
We report an emergent complex hybrid repair of a type A intramural hematoma with a tear of the aortic arch at the site of Kommerell's diverticulum and an aberrant right subclavian artery. We identified a type IA endoleak intraoperatively, which was managed immediately with proximal extension. Performing this operation in the hybrid operating room facilitated optimal surgical management. 相似文献
New chiral heterocyclic compounds with a hexahydro-2H-chromene framework were synthesized by reactions of (1R,2R,6S)-3-methyl-6-(prop-1-en-2-yl)cyclohex-3-ene-1,2-diol with aromatic aldehydes in the presence of montmorillonite clay. The analgesic activity of the compounds was studied in vivo. The majority of these compounds showed significant analgesic activity in the acetic acid-induced writhing test; the compounds containing one hydroxy and one methoxy substituents also showed analgesic activity in the hot-plate test. (2S,4aR,8R,8aR)-2-(3-Hydroxy-4-methoxyphenyl)-4,7-dimethyl-3,4,4a,5,8,8a-hexahydro-2H-chromene-4,8-diol was as effective as the diclofenac sodium reference taken in the same dose in both tests. It has low acute toxicity and is very promising for further development. 相似文献
Delayed wound healing is one of the most challenging complications of diabetes mellitus (DM) in clinical medicine. This study has aimed to evaluate the effects of low-level laser therapy (LLLT) on human skin fibroblasts (HSFs) cultured in a high glucose concentration. HSFs were cultured either in a concentration of physiologic glucose (5.5 mM/l) or high glucose media (11.1 and15?mM/l) for either 1 or 2 weeks after which they were subsequently cultured in either the physiologic glucose or high concentration glucose media during laser irradiation. LLLT was carried out with a helium–neon (He–Ne) laser unit at energy densities of 0.5, 1, and 2 J/cm2, and power density of 0.66 mW/cm2 on 3 consecutive days. HSFs’ viability and proliferation rate were evaluated with the dimethylthiazol-diphenyltetrazolium bromide (MTT) assay. The LLLT at densities of 0.5 and 1 J/cm2 had stimulatory effects on the viability and proliferation rate of HSFs cultured in physiologic glucose (5.5 mM/l) medium compared to their control cultures (p?=?0.002 and p?=?0.046, respectively). All three doses of 0.5, 1, and 2 J/cm2 had stimulatory effects on the proliferation rate of HSFs cultured in high glucose concentrations when compared to their control cultures (p?=?0.042, p?=?0.000, and p?=?0.000, respectively). This study showed that HSFs originally cultured for 2 weeks in high glucose concentration followed by culture in physiologic glucose during laser irradiation showed enhanced cell viability and proliferation. Thus, LLLT had a stimulatory effect on these HSFs. 相似文献
